Pull timer core updates from Thomas Gleixner:

 - Address the inconsistent shutdown sequence of per CPU clockevents on
   CPU hotplug, which only removed it from the core but failed to invoke
   the actual device driver shutdown callback. This kept the timer
   active, which prevented power savings and caused pointless noise in
   virtualization.

 - Encapsulate the open coded access to the hrtimer clock base, which is
   a private implementation detail, so that the implementation can be
   changed without breaking a lot of usage sites.

 - Enhance the debug output of the clocksource watchdog to provide
   better information for analysis.

 - The usual set of cleanups and enhancements all over the place
